Error compiling for board WEMOS D1 MINI ESP32.
Trying to use This project: https://github.com/witnessmenow/ESP32-Trinity/blob/master/examples/BuildingBlocks/Text/ScrollingText/ScrollingText.ino will not compile with 2.0.7 (or 2.0.6). Using version 2.0.5 of that library does work, however. Get the following error: /Users/tom/Arduino/libraries/ESP32_HUB75_LED_MATRIX_PANEL_DMA_Display/ESP32-HUB75-MatrixPanel-I2S-DMA.cpp:10:21: note: #pragma message: Compiling for original (released 2016) 520kB SRAM ESP32.
